FOOD PRESERVATIVE.

Application filed November 30, 1926. I Serial No. 151,808.

This invention relates to an improvement in food containers designed to be constructed for use as mating sectlons, each sectlon being sealed against the other with the sections readily separable at will so that the diflerent varieties of foods in the respective sections may be rendered available as needed.

The invention comprises duplicate sec-- The invention is illustrated in the accom-- panying drawings in which? Figure l is a face view of the unit, the cooperating interlocking means of the sec tions being shown in dotted outline.

Figure 2 is an edge view of the connected sections.

Figure 3 is a broken view in elevation, partly, in section,-of one of the sections, showing the means for permitting access to the contents of the section.

Figure 4 is a transverse section on the I line 4-4 of Figure l.

The food carrier comprises substantially duplicate sections 1 and 2 of metal and preferably of rectangular outline, the sections being interiorly divided by transverse partitions 3 forming food receiving chambers 4. One wall, preferably the inner wall in the assembled relation of the sections, is scored along the line 5 to permit said wall to be bodily separated from the sections, and in section forming relation this wall is retained by a sealing strip 6 adapted to be torn from its sealing position through the use of the usual key 7. The strip extends throughout the margin of the removable wall so that,

when said wall is free to be removed on the displacement of the sealing strip, the contents of the. food compartments 4 are readily accessible. Y

The inner Wall of one of the sections is formed with a keeper in the form of a locking strip 8 secured at its ends to the section and an intermediate raised portion 9, the locking section extending transverse the wall. The companion section is formed on its inner wall with a tongue 10 extending longitudinally thereof and secured at one end, the opposite end 11 being free so that it may be passed beneath the raised portion 9 of the locking strip 8. r

The sealing strip 6 on one of the sections is formed near the end of that section and at the upper and lower edges of the wall with recesses 12, the sealing strip of the other section being formed at similar points on such other section with projections 13.

The sections are assembled in unit form by sliding such sections relative to each other, this movement causing the tongue 11 to ride 'into the raised portion 9 of the looking strip '8 and being continued until the projections 13 ride into the recesses 12. The sections are thus interlocked against casual separation and may be readily and convenientlyhandled as a unit.

It is primarily intended, though not of course obligatory, that the respective sections contain foods of difierentcharacters so that the desired food may be readily ob tained by selecting the particular section. The respective compartments 4 of the sections will contain different foods of the same general character which may be introduced into the sections in cooked form, for example by the application of steam which will force the air from the compartment to a greater or less degree through the suitably formed vent which, being sealed while the section is heated, causes a rarefied air condition within the chamber when the section is cooled,

thus tending to a preservation of the foods.

It is entirely possible and within the spirit of the present invention that instead of using a removable plate for all the compartments of a section, each compartment may be provided with an independent closing plate secured by a sealing strip so that only the food of a particular compartment or compartments desired may be exposed for use while the remaining compartments of the particular section are maintained in their original sealed condition. This detail requires no illustration as it is obviously merely the provision of a series of sealing plates and the use of a sealing strip-6 for each such plate.

What I claim as new is: A food container made up of a plurality of similar sections adapted to be arranged in superimposed relation, a locking strip secured on one face ofone section, and a locking tongue adapted to engage beneath sald cooperation, whereby the sections are held against endwise or lateral displacement. I

In testimony whereof I aflix my signature.
